Turbophoresis (wikipedia)

Turbo: Turbine, a rotary engine actuated by the reaction or impulse or both of a current of fluid (as water, steam, or air) subject to pressure and usually made with a series of curved vanes on a central rotating spindle.

A theory of particle deposition in turbulent pipe flow YOUNG J., LEEMING A. Abstract We describe a theory of particle deposition based formally on the conservation equations of particle mass and momentum. These equations are formulated in an Eulerian coordinate system and are then Reynolds averaged, a procedure which generates a number of turbulence correlations, two of which are of prime importance. One represents 'turbulent diffusion' and the other 'turbophoresis', a convective drift of particles down gradients of mean-square fluctuating velocity. Turbophoresis is not a small correction; it dominates the particle dynamic behaviour in the diffusion-impaction and inertia-moderated regimes. Adopting a simple model for the turbophoretic force, the theory is used to calculate deposition from fully developed turbulent pipe flow.
